Required Methods

fn method(&self) -> &str

The method name this provider handles (e.g., “password”, “token”, “solana”).

fn create( &self, rng: &Rng, config: &HashMap<String, String>, ) -> Result<HashMap<String, String>>

Create stored credentials from configuration. Called during CREATE AUTHENTICATION ... FOR USER .... The rng parameter provides deterministic randomness in test mode.

fn authenticate( &self, stored: &HashMap<String, String>, credentials: &HashMap<String, String>, ) -> Result<AuthStep>

Authenticate a user given their stored credentials and the presented credentials.

For single-step methods (password, token), this returns Authenticated or Failed. For challenge-response methods, this may return Challenge with data the client must respond to, followed by a second call with the response.
